Synopsis: 18 year-old HUI, a wannabe Instagram model, is stuck taking care of her older autistic brother XIANG on Matsu Island in Taiwan, as her mother has ran away and her father only cares for his business. At her amateur play where none of her followers show up, her MOTHER suspiciously appears – Mother started her own cult, who pray to the water goddess Matsu, but is in trouble because she claimed that the Goddess would appear last week. She proposes that Hui act as the Goddess for one hour in exchange for taking care of Xiang. Hui readily agrees.

They manage to fool the cult, but when Hui sees how much they love her, she decides to move into the cult compound with Xiang, usurping Mother’s position as the leader. Mother furiously launches a war with Hui, where Mother makes Hui fat and Hui forces Mother to shave her head. Meanwhile, Xiang is glad to be near Goddess Matsu, as he is afraid of water and learning how to swim.

Father arrives to stop the madness but makes things worse. When her parents team up, things turn fatal, and Hui must decide if she will sink to her parents’ evil ways…
